1. A system for preventative dental treatment comprising:
a radiation source configured to generate a radiation having a wavelength in one or more of a first range between 100 and 500 nm and a second range between 8,000 and 12,000 nm;
a diamond optic disposed to accept the radiation at a first end, internally reflect the radiation, and contact a dental hard tissue with one or more sides of the diamond optic; and, wherein the diamond optic is configured to couple at least a portion of the radiation into the dental hard tissue when placed in contact with the dental hard tissue on the one or more sides;
a cooling system configured to cool the diamond optic, wherein the cooling system comprises:
a fluidic pathway in fluidic communication with and sealed about the diamond optic; and
a coolant configured to flow within the fluidic pathway and come into direct contact with the diamond optic; and
a controller configured to control at least one parameter of the radiation to raise a temperature of a surface of the dental hard tissue to a temperature that is greater than 400° Celsius.
